A automated tire chaining assembly includes a housing that is positioned above a respective one of a plurality of tires on a vehicle. A chain is formed into a closed loop and the chain extending through each of an entry and an exit of the housing. The chain is positionable in a deployed position having the chain being dropped downwardly around the respective tire to enhance traction of the tire on a slippery surface. A deploying unit is movably attached to the housing and the deploying unit engages the chain. The deploying unit urges the chain between the stored position and the deployed position. Additionally, the chain extends in front of the respective tire when the deploying unit urges the chain into the deployed position thereby facilitating the respective tire to roll over the chain.

Described is a shielding installation device in large tires and a shielding installation method in large tires. The device comprises a shaft, a reducer, a motor, a base, and a frame. The shielding installation method comprises different sequential steps, configured for installation of shielding on the thread of a large tire. The device and method of use of this device can allow a safe and practical installation of shielding in large vehicles, solving the serious safety problem related to traditional techniques of installation of this element.

A unit for rapid deployment and retraction of chain traction systems for vehicles includes a pneumatic cylinder having a cylindrical chamber enclosing a piston that is pneumatically-movable bidirectionally. A control rod coupled at one end to the piston passes through an end of the chamber and is coupled to a rack linearly movable within a sealed, grease-containing case. The rack is formed from a series of equally-spaced roller pins secured between parallel walls of a rack frame. The roller pins of the rack engage a sprocket affixed to a rotatable shaft to which is rigidly coupled an actuator arm of the rapidly-deployable vehicle ice and snow chain traction system. As the rack is moved back and forth, the actuator arm swings through an arc that—depending on the displacement of the control rod and the length of the rack, can be greater than 180 degrees.

The tool includes an elongate rigid bar with fixed chain leaders extending from the bar near ends of the bar. A removable chain leader is provided between these two fixed chain leaders. In one form of the invention, the bar is hollow and a pin translates within this hollow core. A slot in the bar allows a proximal link of the removable chain leader to pass into the hollow core of the bar where the pin can removably capture this proximal link. Because the removable chain leader is provided on the bar, it can initially be captured to the bar for use along with the fixed chain leaders to position a tire chain onto a dual wheel pair. Then, the removable leader can be removed from the bar and act as a handle on a middle elongate section of the tire chain to assist in connection thereof.

An external tensioning anti-skid chain system for an automobile, whose characteristics include a number of U-shaped anti-skid boards with the same structure and a set of tightening mechanisms. The two vertical edges of the U-shaped anti-skid plate are attached to the inside and outside of a tire. The first section and the last section of the U-shaped anti-skid plate are connected by a buckle structure. The tightening mechanism is installed between two adjacent U-shaped anti-skateboards, and the U-shaped anti-skid plates are mutually connected by connection rings. The anti-skid chain system has a simple structure, making installation and disassembly very easy.
